The history of alphabetic writing goes back to the consonantal writing system used for Semitic languages in the Levant in the 2nd millennium BCE. Most or nearly all alphabetic scripts used throughout the world today ultimately go back to this Semitic proto-alphabet.[1] Its first origins can be traced back to a Proto-Sinaitic script developed in Ancient Egypt to represent the language of Semitic-speaking workers in Egypt. This script was partly influenced by the older Egyptian hieratic, a cursive script related to Egyptian hieroglyphs.[2][3]

Mainly through Phoenician and Aramaic, two closely related members of the Semitic family of scripts that were in use during the early first millennium BCE, the Semitic alphabet became the ancestor of multiple writing systems across the Middle East, Europe, northern Africa and South Asia.

Some modern authors distinguish between consonantal scripts of the Semitic type, called "abjads", and "true alphabets" in the narrow sense,[4][5] the distinguishing criterion being that true alphabets consistently assign letters to both consonants and vowels on an equal basis, while in an abjad each symbol usually stands for a consonant. In this sense, the first true alphabet was the Greek alphabet, which was adapted from the Phoenician. Latin, the most widely used alphabet today,[6] in turn derives from Greek (by way of Cumae and the Etruscans).

Two scripts are well attested from before the end of the fourth millennium BCE: Mesopotamian cuneiform and Egyptian hieroglyphs. Both were well known in the part of the Middle East that produced the first widely used alphabet, the Phoenician. There are signs that cuneiform was developing alphabetic properties in some of the languages it was adapted for, as was seen again later in the Old Persian cuneiform script, but it now appears these developments were a sideline and not ancestral to the alphabet.[citation needed] The Byblos syllabary has suggestive graphic similarities to both hieratic Egyptian and to the Phoenician alphabet, but as the Byblos syllabary is undeciphered, little can be said about its role, if any, in the history of the alphabet.[citation needed]

By 2700 BCE, the ancient Egyptians had developed the hieroglyphic writing system. Hieroglyphs are employed in three ways in Ancient Egyptian texts: as logograms (ideograms) that represent a word denoting an object pictorially depicted by the hieroglyph; more commonly as phonograms writing a sound or sequence of sounds; and as determinatives (which provide clues to meaning without directly writing sounds).[7] Since vowels were mostly unwritten, the hieroglyphs which indicated a single consonant could have been used as a consonantal alphabet (or "abjad"). This was not done when writing the Egyptian language, but seems to have been significant influence[citation needed] on the creation of the first alphabet (used to write a Semitic language). All subsequent alphabets around the world have either descended from this first Semitic alphabet, or have been inspired by one of its descendants (i.e. "stimulus diffusion"), with the possible exception of the Meroitic alphabet, a 3rd-century BCE adaptation of hieroglyphs in Nubia to the south of Egypt – though even here many scholars suspect the influence of the first alphabet.[citation needed]

The Proto-Sinaitic script of Egypt has yet to be fully deciphered. However, it may be alphabetic and probably records the Canaanite language. The oldest examples are found as graffiti in the Wadi el Hol and date to perhaps 1850 BCE.[8] The table below shows hypothetical prototypes of the Phoenician alphabet in Egyptian hieroglyphs. Several correspondences have been proposed with Proto-Sinaitic letters.

This Semitic script adapted Egyptian hieroglyphs to write consonantal values based on the first sound of the Semitic name for the object depicted by the hieroglyph (the "acrophonic principle").[9] So, for example, the hieroglyph per ("house" in Egyptian) was used to write the sound [b] in Semitic, because [b] was the first sound in the Semitic word for "house", bayt.[10] The script was used only sporadically, and retained its pictographic nature, for half a millennium, until adopted for governmental use in Canaan. The first Canaanite states to make extensive use of the alphabet were the Phoeniciancity-states and so later stages of the Canaanite script are called Phoenician. The Phoenician cities were maritime states at the center of a vast trade network and soon the Phoenician alphabet spread throughout the Mediterranean. Two variants of the Phoenician alphabet had major impacts on the history of writing: the Aramaic alphabet and the Greek alphabet.[11]

The Phoenician and Aramaic alphabets, like their Egyptian prototype, represented only consonants, a system called an abjad. The Aramaic alphabet, which evolved from the Phoenician in the 7th century BCE as the official script of the Persian Empire, appears to be the ancestor of nearly all the modern alphabets of Asia:

By at least the 8th century BCE the Greeks borrowed the Phoenician alphabet and adapted it to their own language,[14] creating in the process the first "true" alphabet, in which vowels were accorded equal status with consonants. According to Greek legends transmitted by Herodotus, the alphabet was brought from Phoenicia to Greece by Cadmos. The letters of the Greek alphabet are the same as those of the Phoenician alphabet, and both alphabets are arranged in the same order.[14] However, whereas separate letters for vowels would have actually hindered the legibility of Egyptian, Phoenician, or Hebrew, their absence was problematic for Greek, where vowels played a much more important role.[15] The Greeks used for vowels some of the Phoenician letters representing consonants which weren't used in Greek speech. All of the names of the letters of the Phoenician alphabet started with consonants, and these consonants were what the letters represented, something called the acrophonic principle.

However, several Phoenician consonants were absent in Greek, and thus several letter names came to be pronounced with initial vowels. Since the start of the name of a letter was expected to be the sound of the letter, in Greek these letters now stood for vowels.[citation needed] For example, the Greeks had no glottal stop or h, so the Phoenician letters ’alep and he became Greek alpha and e (later renamed e psilon), and stood for the vowels /a/ and /e/ rather than the consonants /ʔ/ and /h/. As this fortunate development only provided for five or six (depending on dialect) of the twelve Greek vowels, the Greeks eventually created digraphs and other modifications, such as ei, ou, and o (which became omega), or in some cases simply ignored the deficiency, as in long a, i, u.[16]

Several varieties of the Greek alphabet developed. One, known as Western Greek or Chalcidian, was used west of Athens and in southern Italy. The other variation, known as Eastern Greek, was used in Asia Minor (also called Asian Greece i.e. present-day aegean Turkey). The Athenians (c. 400 BCE) adopted that latter variation and eventually the rest of the Greek-speaking world followed. After first writing right to left, the Greeks eventually chose to write from left to right, unlike the Phoenicians who wrote from right to left. Many Greek letters are similar to Phoenician, except the letter direction is reversed or changed, which can be the result of historical changes from right-to-left writing to boustrophedon to left-to-right writing.

Greek is in turn the source for all the modern scripts of Europe. The alphabet of the early western Greek dialects, where the letter eta remained an h, gave rise to the Old Italic and from these Old Roman alphabet derived. In the eastern Greek dialects, which did not have an /h/, eta stood for a vowel, and remains a vowel in modern Greek and all other alphabets derived from the eastern variants: Glagolitic, Cyrillic, Armenian, Gothic (which used both Greek and Roman letters), and perhaps Georgian.[17]

Although this description presents the evolution of scripts in a linear fashion, this is a simplification. For example, the Manchu alphabet, descended from the abjads of West Asia, was also influenced by Korean hangul, which was either independent (the traditional view) or derived from the abugidas of South Asia. Georgian apparently derives from the Aramaic family, but was strongly influenced in its conception by Greek. A modified version of the Greek alphabet, using an additional half dozen demotic hieroglyphs, was used to write Coptic Egyptian. Then there is Cree syllabics (an abugida), which is a fusion of Devanagari and Pitman shorthand developed by the missionary James Evans.[18]

A tribe known as the Latins, who became known as the Romans, also lived in the Italian peninsula like the Western Greeks. From the Etruscans, a tribe living in the first millennium BCE in central Italy, and the Western Greeks, the Latins adopted writing in about the seventh century. In adopted writing from these two groups, the Latins dropped four characters from the Western Greek alphabet. They also adapted the Etruscan letterF, pronounced 'w,' giving it the 'f' sound, and the Etruscan S, which had three zigzag lines, was curved to make the modern S. To represent the G sound in Greek and the K sound in Etruscan, the Gamma was used. These changes produced the modern alphabet without the letters G, J, U, W, Y, and Z, as well as some other differences.

C, K, and Q in the Roman alphabet could all be used to write both the /k/ and /ɡ/ sounds; the Romans soon modified the letter C to make G, inserted it in seventh place, where Z had been, to maintain the gematria (the numerical sequence of the alphabet). Over the few centuries after Alexander the Great conquered the Eastern Mediterranean and other areas in the third century BCE, the Romans began to borrow Greek words, so they had to adapt their alphabet again in order to write these words. From the Eastern Greek alphabet, they borrowed Y and Z, which were added to the end of the alphabet because the only time they were used was to write Greek words.

The Anglo-Saxons began using Roman letters to write Old English as they converted to Christianity, following Augustine of Canterbury's mission to Britain in the sixth century. Because the Runicwen, which was first used to represent the sound 'w' and looked like a p that is narrow and triangular, was easy to confuse with an actual p, the 'w' sound began to be written using a double u. Because the u at the time looked like a v, the double u looked like two v's, W was placed in the alphabet by V. U developed when people began to use the rounded U when they meant the vowel u and the pointed V when the meant the consonant V. J began as a variation of I, in which a long tail was added to the final I when there were several in a row. People began to use the J for the consonant and the I for the vowel by the fifteenth century, and it was fully accepted in the mid-seventeenth century.

Simplified relationship between various scripts leading to the development of modern lower case of standard Latin alphabet and that of the modern variants, Fraktur (used in Germany until recently) and Gaelic (Ireland). Several scripts coexisted such as half-uncial and uncial, which derive from Roman cursive and Greek uncial, and Visigothic, Merovingian (Luxeuil variant here) and Beneventan. The Carolingian script was the basis for blackletter and humanist. It should be noted that what is commonly called "gothic writing" is technically called blackletter (here Textualis quadrata) and is completed unrelated to Visigothic script.
The letter j is i with a flourish; u and v are the same letter in early scripts and were used depending on their position in insular half-uncial and caroline minuscule and later scripts; w is a ligature of vv; in insular the runewynn is used as a w (three other runes in use were the thorn (þ), ʻféʼ (ᚠ) as an abbreviation for cattle/goods and maðr (ᛘ) for man).
The letters y and z were very rarely used; in particular þ was written identically to y, so y was dotted to avoid confusion, the dot was adopted for i only after late-Caroline (protgothic), in Benevetan script the macron abbreviation featured a dot above.
Lost variants such as r rotunda, ligatures and scribal abbreviation marks are omitted, long s is shown when no terminal s (surviving variant) is present.Humanist script was the basis for venetian types which changed little until today, such as times new roman (a serifed typeface))

The order of the letters of the alphabet is attested from the fourteenth century BCE in the town of Ugarit on Syria’s northern coast.[19] Tablets found there bear over one thousand cuneiform signs, but these signs are not Babylonian and there are only thirty distinct characters. About twelve of the tablets have the signs set out in alphabetic order. There are two orders found, one of which is nearly identical to the order used for Hebrew, Greek and Latin, and a second order very similar to that used for Ethiopian.[20]

It is not known how many letters the Proto-Sinaitic alphabet had nor what their alphabetic order was. Among its descendants, the Ugaritic alphabet had 27 consonants, the South Arabian alphabets had 29, and the Phoenician alphabet 22. These scripts were arranged in two orders, an ABGDE order in Phoenician and an HMĦLQ order in the south; Ugaritic preserved both orders. Both sequences proved remarkably stable among the descendants of these scripts.

One modern national alphabet that has not been graphically traced back to the Canaanite alphabet is the Maldivian script, which is unique in that, although it is clearly modeled after Arabic and perhaps other existing alphabets, it derives its letter forms from numerals. Another is the Korean Hangul, which was created independently in 1443. The Osmanya alphabet was devised for Somali in the 1920s by Osman Yusuf Kenadid, and the forms of its consonants appear to be complete innovations.

Among alphabets that are not used as national scripts today, a few are clearly independent in their letter forms. The Zhuyin phonetic alphabet derives from Chinese characters. The Santali alphabet of eastern India appears to be based on traditional symbols such as "danger" and "meeting place", as well as pictographs invented by its creator. (The names of the Santali letters are related to the sound they represent through the acrophonic principle, as in the original alphabet, but it is the final consonant or vowel of the name that the letter represents: le "swelling" represents e, while en "thresh grain" represents n.)

In early medieval Ireland, Ogham consisted of tally marks, and the monumental inscriptions of the Old Persian Empire were written in an essentially alphabetic cuneiform script whose letter forms seem to have been created for the occasion.

^"there are languages for which an alphabet is not an ideal writing system. The Semitic abjads really do fit the structure of Hebrew, Aramaic, and Arabic very well, [more] than an alphabet would [...], since the spelling ensures that each root looks the same through its plethora of inflections and derivations."
